my dad was doing a 450+ mile commute each week in a duelly turbo diesel F350 getting 15 mpg. He recently bought a 92 civic cx that has been getting 36 mpg. He wants to eco mod it after I've shown him what some of you guys are getting. The car will pay for its self in a year.
I've also gotten my mom to drive more consciously. Slowing down earlier for red lights, accelerating lightly, and she's getting about 30 mpg in a 05 toyota avalon xls. which surprisingly has a cd of .29
